Introduction to Choreographies

'A mass of dancers dance individually and concurrently following a choreography, creating a masterpiece collaboratively. Choreographies are a framework to promote a protocol-guided programming for no single point of failure. Montesi's book starts from a friendly introduction to formal methods for beginners and covers comprehensive choreography theories—from the simple choreographies to the advanced extensions. Highly recommended for the undergraduate and graduate computer science students as well as developers of web services.' Nobuko Yoshida, Christopher Strachey Chair of Computing, University of Oxford

'Distributed systems are the norm today. Choreographies govern how autonomous parts of distributed systems that operate concurrently may communicate with each other. However, it is not always clear whether all communication participants comply with a given choreography design. This book comes to the remedy. Fabrizio Montesi, pioneer of choreographic programming with the Jolie language and microservices community leader, establishes a uniform theory and a notation for choreographies – not only to specify their protocols, but also to check participant conformance and prove desired properties including communication safety and freedom from starvation. Read this book if you want to learn or teach these concepts en route to more robust and more understandable Distributed Systems, and apply its concepts in practice if you want to prove that your language, middleware, and tool creations work as designed.'
